Submission + - Bank Of England Accidentally E-mails Top-Secret Brexit Plan to the Guardian (theguardian.com)
In retrospect, maybe the first rule should have been "you don't accidentally e-mail 'Project Bookend' to a news agency", because as the Guardian reports, one of its editors opened his inbox and was surprised to find a message from the BOE's Head of Press Jeremy Harrison outlining the UK financial market equivalent of the Manhattan project.
Project Bookend is a secret (or 'was' a secret) initiative undertaken by the BOE to study what the fallout might be from a potential 'Brexit', but if anyone asked what Sir Jon Cunliffe and a few senior staffers were up to, they were instructed to say that they were busy investigating "a broad range of European economic issues."
